Abstract
The utility model relates to a U-shaped groove opening ice resisting cone, which is composed of a cone body, a groove sealing board, a U-shaped groove, a rubber sheet, a bolt, a jacket leg, and a cable protective tube or a vertical pipe, the U-shaped groove and the groove sealing board are arranged on the cone body of the ice resisting cone, not only the requirement of field installation of the cable protective tube and the vertical pipe at sea can be achieved, but also the integrity of the structure of the ice resisting cone can be kept, and the cable protective tube and the vertical pipe and the jacket structure are protected. Compared with the prior ice resisting cone, the utility model can keep the cable protective tube or the vertical pipe to be assembled on site at sea, simultaneously keep the integrity of the structure of the ice resisting cone, ensure the ice resisting effect of the whole ice resisting cone, and reduce the construction difficulty degree at sea. The utility model can be widely used in the oil and gas field development projects in the heavy ice region sea area.
Description
Technical field
The utility model belongs to the equipment that the ocean jacket platform recovers the oil, particularly a kind of U-shaped anti-ice piton of slotting.
Background technology
At present, oil, gas field development that marine site, thick ice formation generally adopts jacket platform to carry out because thick ice is huge to the destruction of jacket structure, therefore need be provided with cable protecting tube or the standpipe that anti-ice piton comes armour tubing frame leg post and arranges along leg post direction.Existing anti-ice piton generally is designed to the tapered steel structure, is welded on after land is prefabricated on the jacket leg, and its operating point absolute altitude is identical with the mean sea level absolute altitude.If have cable protecting tube or standpipe to pass anti-ice piton, existing anti-ice piton design all is that a hole is opened in the relevant position on cone, on land when prefabricated, is installed on the jacket in advance after cable protecting tube or standpipe passed anti-ice piton.If project is left to marine scene in advance with cable protecting tube or standpipe and installs, existing anti-ice piton design then can't realize, so standpipe and cable protecting tube bottom all have one section bend pipe, passes the hole on the anti-ice piton at sea in the time of can't on-the-spotly installing.Therefore, existing anti-ice piton design only is applicable to and adopts pre-mode of installing that standpipe and cable protecting tube are installed when land formation.
Summary of the invention
The purpose of this utility model provides a kind of U-shaped anti-ice piton of slotting; by U-lag and sealing groove plate are set on the cone of anti-ice piton; both can satisfy the marine field erected requirement of cable protecting tube and standpipe; the integrality that has kept anti-ice piton structure again plays the effect of protection cable protecting tube, standpipe and jacket structure.
The utility model is made up of cone, sealing groove plate, U-lag, rubber skin, bolt, jacket leg, cable protecting tube or standpipe, appearance is the cone (1) of vertical U-lag (3), be welded on the jacket leg (6), sealing, inside is provided with the reinforcement gusset, rubber skin (4) is posted in U-lag (3) inboard, and cable protecting tube or standpipe (7) are housed on the rubber skin (4), and sealing groove plate (2) is arranged on cable protecting tube or the standpipe (7).
The utility model is with respect to existing anti-ice piton, cable protecting tube or standpipe can be left to marine scene in advance and install, and kept the integrality of anti-ice piton structure simultaneously, guaranteed the anti-ice effect of whole anti-ice piton, can also reduce the offshore construction difficulty.In the oil in marine site, thick ice formation, gas field development project, but extensive use.

The specific embodiment
As shown in Figure 1, the utility model can satisfy one or more cable protecting tube or the field erected requirement of standpipe (7) at sea, its appearance is the cone (1) of vertical U-lag (3), be welded on the jacket leg (6), sealing, inside is provided with the reinforcement gusset, for the anti-ice piton that has many cable protecting tubes or standpipe (7) to pass, can open 1-5 U-lag (3) to satisfy installation requirement in the surperficial relevant position of cone (1); Key of the present utility model is the design of U-lag (3) and sealing groove plate (2), rubber skin (4) is posted in U-shaped fluting (3) inboard, rubber skin (4) thickness is from 1 millimeter to 50 millimeters, its thickness selects with marine installation environment situation bigger relation is arranged, for more abominable marine installing environmental conditions, the impact force of generation in the time of can selecting thicker rubber skin (4) to cushion when cable protecting tube or standpipe (7) are marine to be installed with the collision of anti-ice piton, for marine installing environmental conditions preferably, then can select thin rubber skin (4), the internal diameter of the U-lag (3) behind the stickup rubber skin (4) is bigger slightly than the external diameter (containing corrosion-inhibiting coating thickness) of cable protecting tube that needs to install or standpipe (7), its theoretical gap is not less than 2 millimeters, this gap is in order to eliminate making and the influence of construction error, and helps the sea installation of cable protecting tube or standpipe (7).U-lag (3) is identical with the material of cone (1), adopts all that steel plate is prefabricated to form.
As Fig. 2,3, shown in 4, sealing groove plate (2) has three kinds of connected modes with U-lag (3): full welding, bolt (5) connects or the first half welding the latter half bolt (5) connects, because the tidal level in the identical marine site of different times meeting difference is very big, sealing groove plate (2) type of attachment choose the marine set-up time that depends primarily on cable protecting tube or standpipe (7), bolt relatively is suitable for connecting under water, welding then is suitable for connection waterborne, therefore, if the tidal level in this marine site in the period of installation is very low, the U-lag of anti-ice piton is exposed on the sea fully, sealing groove plate (2) can be chosen all-welded type of attachment, as tidal level is higher when installing, the U-lag of anti-ice piton is positioned under the water surface fully, sealing groove plate (2) then can be chosen the type of attachment of full bolt (5), when tidal level can be chosen the type of attachment that the first half welding the latter half bolt (5) connects between time between the two.
The utility model the utility model is with respect to existing anti-ice piton, by on the cone (1) of anti-ice piton, U-lag and sealing groove plate being set, cable protecting tube or standpipe can be left to marine scene in advance and install, break through existing anti-ice piton and only be applicable to the present situation that when land formation, adopts pre-mode of installing that cable protecting tube or standpipe (7) are installed.U-lag (3) plays guiding and positioning action when cable protecting tube or standpipe (7) installation; the inboard rubber skin (4) of U-lag (3) can cushion cable protecting tube or standpipe (7) is marine when installing and the impact force of anti-ice piton collision generation; thereby protection U-lag (3) and anti-ice piton; sealing groove plate (2) can be realized the spacing and protective effect after cable protecting tube or standpipe (7) are installed; the integrality that has kept anti-ice piton structure simultaneously; guarantee the anti-ice effect of whole anti-ice piton, can also reduce the offshore construction difficulty.In the oil in marine site, thick ice formation, gas field development project, but extensive use.
